Title: Record handling means for information storage apparatus
IPC: G11B17/28
Filed: 1963-08-13
Abstract: 1,000,778. Random access disc-record stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 13, 1963 [Aug. 15, 1962], No. 31882/63. Heading G5R. To transfer a disc record 10 from a groove in a storage bin 12 along a pneumatically-lubricated guide 36 to a transducing station, an ejector 14 imparts sufficient momentum to the record to carry it to rotatory means 82. The storage bin 12 is movable transversely to a precise position by a piston adder 38 to select the desired record and the ejector 14, which usually applies suction to retain the record, applies pressure to blow it out of the bin. The guide bars 50 are each provided with a record-supporting groove and are formed of foraminous material through which air is forced to provide an air-lubricated path. At the transducing station, the record is rotated by rotatory means 82 after location by means 62 supplied with suction by a valve 63. The arrival of the record is sensed by means 74 which then applies air pressure to a clutch 85 to engage the drive means 82 with the record. The engagement of the means 82 changes over contacts 68, 90 and 91 which:-  (a) de-energize valve 63 and energize valve 70 causing air pressure to be applied to the sides of the device 62;  (b) cause suction to be applied to the face of the rotatory means 82 through tube 94 to grip the record; and (c) cause a motor 84 to start rotating the record relative to a transducer 101. The record is returned to the storage bin either by reversing the above procedure, or by releasing the still-rotating record from the device 82, whereupon it rolls back into the bin under its own momentum.  In an alternative embodiment (Fig. 2, not shown) the record is stored, transferred and transduced in a horizontal plane. In this case, additional guides between the guide-bars 50 support the weight of the record.
